' l SPECIFICATION forming part of Letters Patent No. 230,351, dated July20, 1880,

Application filed June 2, 1880. (No model.) I

To all whom tt may concern:

Be it known that I, ALBERT SEYBERLICI-I, a resident of Feldberg, in theGrand Duchy of Mecklenburg, in the German Empire, have invented new anduseful Improvements in Pneumatic Suction Apparatusfor Medical Purposes,of which the following is a specification.

This invention relates to improvements in pneumatic suction apparatusfor medicwsurgical purposes, and more especially to improvements ofthatportion ot'the apparatus by which the hermetical connection with thelimbs or other part of the body to be treated is produced. f

In the pneumatic suction apparatuswhich was heretofore in use formedico-surgical purposes the mouth-piece consisted of an annular pieceof soft rubber, which was provided at its upper side with pockets intowhich the ends of small levers were inserted, whose outer ends wereengaged by the annular lip or flange of an adjustable screw-collar,while they were fulcrumed at their middle portion to the cylindricalbody of the apparatus, so that by raising or lowering the collar themouth-piece was contracted or enlarged, as required. This constructionof the mouth-piece was found to be objectionable for several reasons. Inthe first place, the edge of the same exerted a cutting actionuponthebody to which the apparatus was applied; secondly, the pockets for thelevers -were liable to be torn, especially when it was attempted toenlarge the mouth-piece, owing to the fact that the pockets did not formsuch a component portion of the mouth-piece that they could resistthe'strain exerted thereon by the levers.

The object of this invention is to remove these objections and to soimprove the construction of the mouth-piece that it can be tightly, yetwithout any inconvenience, applied to any part of the body to betreated, and also that the treating of the lever-pockets be dispensedwith. l

The invention consists of an annular elastic mouth-piece provided withan enlarged rim at its inner end, said mouth-piece being provided at theunder side with pockets for the adjusting-levers, said pockets extendinginwardly from a cylindrical extension of the mouthpiece, by which theconnection with the cylindrical main portion of the apparatus is made.

In the accompanying drawings, Figurel represents a sectional sideelevation ot my improved pneumatic apparatus for treating portions ofthe body by air-suction. Fig. 2 is a top view of the same, partly inhorizontal section. Fig. 3 is a vertical central section of theapparatus, shown with elastic mouth-piece and bottom, adapted to beapplied to the chest or abdomen. Fig. 4 is a vertical side elevation,

partly in central section, of the apparatus constructed on a largescale, and Fig. 5 is a bottom view of the latter.

, Similar letters of reference indicate corresponding parts.

A in the drawings represents an elastic mouth-piece, ofsoft rubber orother elastic material, and A the cylindrical main portion or recipientof the apparatus, which is made of sheet metal and of any suitable size,so as to be adapted to any portion or the whole of the body.

The apparatus is closed at the lower part, either by a removable bottom,to which the pipe leading to the air-pump, as well as a pressure-gage,is connected, or it is closed by an elastic bottom of thesameconstruction as the mouth-piece, the latter being used more especiallywhen the apparatus is to be applied to the chest or abdomen, as shown inFig. 3.

The mouth-piece A has a cylindrical lower portion or extension, a, bywhich it is secured to the upper part of the main portion or recipientA. The mouth-piece A is provided at the under side with radial pockets6, which open at the circumference of the cylindrical portion and servefor receiving small levers d, which are fulcrumed to a fixed. ring orcollar, f, at the upper part of the main body.

The collar or ring f, to which the levers are are thereby prevented frombeing torn by the levers. The main advantage of the rim consists,however, in the hermetical joint which it forms with the body, the rimadapting itself to the contours of the same without causing the leastinconvenience by cutting.

The levers d are slightly curved and are all engaged at their outer endsby the inwardlybent rim of a cylindrical collar, D, which is movablealong the outer portion of the recipient A, either by means of ascrew-nut, E, which extends over a projection of the upper part of therecipient A, or by means of a worm-wheel which intermeshes with acircumferential toothed ring of the recipient, the ring imparting motionto pinions of vertical adj usting-screws, as shown in Figs. 4 and 5.

The latter construction is more especially designed for apparatus oflarger size, while the screw-nut and collar are preferable for apparatusof smaller size.

The cylinder D engages, by its up-and-down motion, the lever d of themouth-piece, and causes the contraction or enlargement of the same, asshown clearly in Fig. 1, in which the dotted linesindicate the enlargedmouth-piece, while the full-drawn lines indicate it when contracted.

By means of this improved construction of the mouth-piece the pneumaticsuction apparatus may be readily applied to any part of the body, andthe same then exposed to the required treatment without an yinconvenience.

If it be desired that the parts of the body should be treated with heatsimultaneously to A is constructed with double walls, which are heatedby means of steam, hot water, or otherwlse.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In apneumatic suction apparatus, an annular elasticmouth-piece having an enlarged rim at its inner edge, substantially asset forth.

2. In a pneumatic suction apparatus, an elastic annular mouth-piecehaving an interior enlarged rim and pockets which extend at the underside of the mouth-piece from the rim to the outer cylindrical portion ofthe same, substantially as described.

3. In a pneumatic suction apparatus, the combination, of an elasticmouth-piece, A, having an inner enlarged rim, an outer cylindricalportion, and pockets at the under side with fulcrumed levers, with anexterior ring or collar, having inwardly-bent rim to engage the outerends of the lever, and with mechanism, substantially as described,whereby the collar raises or lowers the levers and expands or contractsthe mouth-piece, substantially as set forth.

In testimony whereofI have signed my name to this specification in thepresence of two subscribing witnesses.

ALBERT SEYBERLIOH.
